Worked Example
Example: ₹15,00,000 Salaried Income under New Regime
Calculate final tax liability after standard deduction.
- Apply Salaried Standard Deduction: ₹15,00,000 - ₹75,000 = ₹14,25,000 taxable base.
- Slab 1 (0-4L): ₹0 tax.
- Slab 2 (4-8L): 5% of 4L = ₹20,000.
- Slab 3 (8-12L): 10% of 4L = ₹40,000.
- Slab 4 (12-14.25L): 15% of 2.25L = ₹33,750.
- Sum base tax: ₹20,000 + ₹40,000 + ₹33,750 = ₹93,750.
- Add 4% Health Cess: ₹93,750 * 1.04 = ₹97,500 total tax.

Comprehensive Guide to the Canadian Income Tax & Payroll Calculator
Canadian income tax is calculated by combining federal tax brackets with provincial/territorial income tax rates (e.g. Ontario, British Columbia, Alberta, Quebec). This Canadian Tax Calculator computes combined marginal tax rates, CPP/QPP contributions, EI premiums, and total net take-home pay.
Combined Federal & Provincial Brackets
Every resident in Canada pays federal income tax to the CRA plus provincial tax based on their province of residence on December 31. Taxable income is reduced by the Basic Personal Amount (BPA) at both federal and provincial levels.
The Canadian Income Tax Calculator estimates federal and provincial income tax liability for taxpayers across Canada.
